Answer:

x ≈ 6.6, y ≈ 13.3

Step-by-step explanation:

Using the tangent ratio in the right triangle to find x

tan30° = \frac{opposite}{adjacent} = \frac{BC}{AB} = \frac{x}{11.5} ( multiply both sides by 11.5 )

11.5 × tan30° = x , then

x ≈ 6.6 ( to the nearest tenth )

Using the cosine ratio in the right triangle to find y

cos30° = \frac{adjacent}{hypotenuse} = \frac{AB}{AC} = \frac{11.5}{y} ( multiply both sides by y )

y × cos30° = 11.5 ( divide both sides by cos30° )

y = \frac{11.5}{cos30} ≈ 13.3

Determine which of the following numbers could not represent the probability of an event. Explain your reasoning. (a). 33.3% (b)
statuscvo [17]

Answer:

B and F

Step-by-step explanation:

The simple golden rule that we need to know here is

<em><u>"The probability of any event is always between 0 and 1 inclusive"</u></em>

<em><u /></em>

If an event has a probability of p(x), we can say:

0 \leq p(x) \leq 1

Also, probability is ALWAYS POSITIVE.

Thus,

A) OK because 33.3% is 0.333, which is between 0 and 1

B) NOT OK, because probability isn't negative

C) 0.0002 is in between 0 and 1, so possible

D) 0 probability means it can't happen, so that's okay as well

E) this is a fraction with numerator less than denominator, which means its between 0 and 1, so OK

F) this fraction's numerator is greater than denominator, so it's greater than 1. Probability can't be greater than 1, so NOT OK

Out of these B and F cannot represent the probability of an event
